/**
* This widget shows the historylog for one entry of an application
*
* It takes as parameter either just the id or an array with the following keys:
* - 'id' integer id of the entry
* - 'app' string app-name, defaults to $GLOBALS['egw_info']['flags']['currentapp']
* - 'status-widgets' array with status-values as key and widget names or array with select-options as value,
* all not set stati are displayed via a label-widget - just as text
* You can set $sel_options['status'] to translate the status-values to meaningful labels.
* If status is already used for a field, you can also set options to an other name, eg. 'labels' or 'fields'
*
* If you have a 1:N relation the 'status-widget' entry should be an array with widget types as values (corresponding
* to order and fields used in bo_tracking's field2history array).
